Clearing Cookies & Cache


Browsers store cookies based on your identity and preferences, and build a cache of repeatedly accessed content, like images and scripts. This makes web browsing quicker, but can sometimes cause issues with how pages are displayed, or your ability to access content.

Clearing the cache and deleting cookies will solve many basic issues with websites. However, it will log your browser out of all websites, and working data in online applications (e.g. Google Docs) may be lost if not synced/saved.

To quickly simulate this without logging out of websites, consider trying an Incognito/Private Browsing window first.
